Concentrate supplement for dairy cows in early peripartum and using method thereof

Abstract

The invention discloses concentrate supplement for dairy cows in early peripartum and a using method thereof. A formula of the concentrate supplement contains 17.5% of protein, 4% of fiber, 2.5% of fat, 12% of ash, 3% of calcium, 0.5% of phosphorus, 0.6% of magnesium, 0.8% of potassium, 0.6% of sulphur, 0.1% of sodium and 0.9% of chlorine, wherein the percentages are mass percentages of all the components in the total weight of the concentrate supplement for dairy cows in early peripartum; and the formula also contains 75mg/kg of manganese, 120mg/kg of iron, 32mg/kg of copper, 2.5mg/kg of cobalt, 125mg/kg of zinc, 0.5mg/kg of selenium, 3mg/kg of iodine, 42000IU of vitamin A, 10000IU of vitamin D, 420IU of vitamin E and 50ppm of rumensin. The using method is that the concentrate supplement for dairy cows in early peripartum is used together with corn silage and tall oat grass or hay. The concentrate supplement can improve the blood calcium concentration of cows, provide available energy, reduce energy negative balance, improve fat metabolism, and reduce blood NEFA (Non Esterified Fatty Acid) concentration so as to effectively guarantee the smooth transition of the production phase of the cows.

Description

technical field [0001] The invention relates to a dairy cow peripartum supplementary feed and a using method thereof. Background technique [0002] Whether the cow successfully transitions from the dry period to the lactation period depends largely on the nutrition and feeding management during the perinatal period. Dairy cows enter the peripartum period (3 weeks before delivery), because the fetus is getting bigger and bigger, and the nutritional requirements are gradually increasing, while the feed intake of the cows decreases (15%~30%). In this case, the cows often Obtain energy from mobilizing their own body fat, which is converted into non-esterified fatty acids (NEFA). Excessive non-esterified fatty acids will be converted into ketone bodies and triglycerides, so cows close to giving birth are often in energy Negative balance, leading to a series of postpartum metabolic diseases; at the same time, due to the secretion of colostrum, a large amount of blood calcium is s...
